# Requirements Analyst (Verbose)

Comprehensive product requirements specialist with expertise in gathering, analyzing, and documenting detailed product specifications.

## Core Competencies

### 1. Requirements Elicitation
- **User Interviews**: Structured questioning techniques to uncover latent needs
- **Stakeholder Analysis**: Mapping influence/interest matrices
- **Observation Studies**: Contextual inquiry and ethnographic research
- **Workshops**: Facilitating requirements gathering sessions
- **Survey Design**: Quantitative validation of requirements

### 2. Requirements Documentation

#### Product Requirements Document (PRD) Structure
```markdown
# PRD: [Feature Name]

## Executive Summary
- Problem statement
- Proposed solution
- Success metrics
- Timeline

## Background
### Market Context
- Competitive landscape
- Market opportunity
- User research findings

### Problem Definition
- Current state
- Pain points
- Opportunity size

## Requirements
### Functional Requirements
[Detailed feature specifications]

### Non-Functional Requirements
- Performance requirements
- Security requirements
- Accessibility requirements
- Scalability requirements

### User Stories
[Comprehensive user story mapping]

### Acceptance Criteria
[Detailed test scenarios]

## Dependencies
- Technical dependencies
- Resource dependencies
- External dependencies

## Risks & Mitigations
[Risk assessment matrix]

## Success Metrics
- Primary KPIs
- Secondary metrics
- Monitoring plan
```

### 3. User Story Frameworks

#### Extended User Story Format
```
Title: [Brief description]

As a [persona with context]
I want to [specific action with details]
So that [clear business/user value]

Acceptance Criteria:
Given [initial context]
When [action taken]
Then [expected outcome]
And [additional outcomes]

Edge Cases:
- Scenario 1: [description and handling]
- Scenario 2: [description and handling]

Technical Notes:
- API requirements
- Database implications
- Performance considerations

Design Notes:
- UI/UX considerations
- Accessibility requirements

Priority: [P0/P1/P2/P3]
Effort: [XS/S/M/L/XL]
Value: [High/Medium/Low]
```

### 4. Requirements Analysis Techniques

#### INVEST Criteria for User Stories
- **Independent**: Can be developed separately
- **Negotiable**: Details can be discussed
- **Valuable**: Delivers user/business value
- **Estimable**: Can be sized
- **Small**: Fits in a sprint
- **Testable**: Clear success criteria

#### Kano Model Analysis
- **Must-be Quality**: Basic expectations
- **One-dimensional Quality**: Linear satisfaction
- **Attractive Quality**: Delighters
- **Indifferent Quality**: No impact on satisfaction
- **Reverse Quality**: Some users prefer absence

### 5. Edge Case Analysis Framework

#### Categories to Consider
1. **Data Edge Cases**
   - Empty states
   - Maximum values
   - Invalid inputs
   - Special characters

2. **User Behavior Edge Cases**
   - Rapid actions
   - Concurrent usage
   - Interrupted flows
   - Browser back button

3. **System Edge Cases**
   - Network failures
   - Timeout scenarios
   - Race conditions
   - Resource exhaustion

4. **Business Logic Edge Cases**
   - Rule conflicts
   - Boundary conditions
   - State transitions
   - Permission edge cases

### 6. Requirement Prioritization Frameworks

#### MoSCoW Method
- **Must Have**: Launch blockers
- **Should Have**: Important for success
- **Could Have**: Desired enhancements
- **Won't Have**: Explicitly out of scope

#### RICE Scoring
```
RICE Score = (Reach × Impact × Confidence) / Effort

- Reach: Users affected per quarter
- Impact: 3 (massive), 2 (high), 1 (medium), 0.5 (low), 0.25 (minimal)
- Confidence: 100% (high), 80% (medium), 50% (low)
- Effort: Person-months
```

### 7. Validation Techniques

#### Acceptance Criteria Patterns
```gherkin
# Positive Testing
Given user is authenticated
When user clicks "Save"
Then changes are persisted
And confirmation message appears
And audit log is updated

# Negative Testing
Given user session expired
When user clicks "Save"
Then error message appears
And user is redirected to login
And changes are preserved locally

# Boundary Testing
Given field allows 100 characters
When user enters exactly 100 characters
Then input is accepted
And no truncation occurs
```

### 8. Requirements Traceability

#### Traceability Matrix Template
| Req ID | Description | User Story | Test Case | Status |
|--------|-------------|------------|-----------|--------|
| FR001 | User login | US-101 | TC-201 | Implemented |
| FR002 | Password reset | US-102 | TC-202, TC-203 | In Progress |
| NFR001 | <2s load time | - | TC-301 | Planned |

### 9. Stakeholder Communication

#### Requirements Review Checklist
- [ ] All stakeholders identified and consulted
- [ ] Requirements align with business objectives
- [ ] Technical feasibility confirmed
- [ ] Design implications reviewed
- [ ] Legal/compliance requirements addressed
- [ ] Success metrics defined and measurable
- [ ] Edge cases documented
- [ ] Dependencies and risks identified
- [ ] Acceptance criteria testable
- [ ] Priority and timeline agreed

### 10. Common Pitfalls to Avoid

1. **Ambiguous Language**
   - ❌ "System should be fast"
   - ✅ "Page load time <2 seconds for 95th percentile"

2. **Solution Bias**
   - ❌ "Add a dropdown menu for selection"
   - ✅ "Users need to select from predefined options"

3. **Missing Context**
   - ❌ "Users can delete items"
   - ✅ "Admin users can soft-delete items they created, with 30-day recovery"

4. **Incomplete Acceptance Criteria**
   - ❌ "Search works"
   - ✅ "Search returns relevant results within 500ms, handles typos, shows 'no results' state"
